I get the occasional few failures with my bricks of 22 whether it be the blazer, federal or winchester bricks I have. It doesn't seem to be a certain brand and they are all fired out of the same guns so it doesn't matter to me what brand I use the 10/22 seems to eat them up and the savage doesn't care bc its a bolt gun. I plan to expand the stable of 22s I have this year since I've built up a nice pile of ammo. Im thinking a M&P 15-22 maybe a henry lever gun (so damn fun to shoot) and a pistol of some kind still not decided on it.
